Benzimidazole-functionalized fluorescent probe for rapid detection of 2,4,6-trinitrophenol and Ag+ in semiaqueous medium [PDF]

Journal of the Serbian Chemical Society, 2021
In this study, a simple fluorescent chemosensor with good fluorescence properties was synthesized, and was used to develop a sensitive and selective sensor, for the determination of 2,4,6-trinitrophenol (TNP) and Ag+ in THF/H2O medium, based on the ...

Diabetes reversal by inhibition of the low-molecular-weight tyrosine phosphatase. [PDF]

, 2017
Obesity-associated insulin resistance plays a central role in type 2 diabetes. As such, tyrosine phosphatases that dephosphorylate the insulin receptor (IR) are potential therapeutic targets.

Quinoline-2-carbaldehyde [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
The title compound, C(10)H(7)NO, crystallizes with two almost planar mol-ecules (A and B) in the asymmetric unit (r.m.s. deviations = 0.018 and 0.020 Å). In the crystal, the A mol-ecules are linked by weak C-H⋯O inter-actions, thereby generating C(9) [001] chains. The B mol-ecules do not exhibit any directional bonding inter-actions.

Carbon-13 n.m.r. investigation on the nitrogen methylation of the mono- and diazanaphthalenes [PDF]

, 1977
The 13C n.m.r. spectra of the N-methylated mono- and diazanaphthalenes have been recorded and analysed. It has been shown that N-methylation as well as N-protonation in cinnoline occur predominantly at the -nitrogen atom.

Quinoline-8-sulfonamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title compound, C(9)H(8)N(2)O(2)S, the sulfamoyl NH(2) group is involved in intra-molecular N-H⋯N and inter-molecular N-H⋯O hydrogen bonding. In the crystal, molecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers, which are further associated through π-π stacking inter-actions between the quinoline benzene rings ...

Isolation and Reactivity of a Square‐Planar Trisamido Silane

Angewandte Chemie, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...
